SecurityAttribute Class

Definition

Namespace:

System.Security.Permissions

Assembly:

System.Runtime.dll

Source:

SecurityAttribute.cs

Caution

Code Access Security is not supported or honored by the runtime.

Specifies the base attribute class for declarative security from which CodeAccessSecurityAttribute is derived.

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

Notes to Implementers

When you inherit from SecurityAttribute, you must override CreatePermission().

Constructors

SecurityAttribute(SecurityAction)

Initializes a new instance of SecurityAttribute with the specified SecurityAction.

Properties

Action	Gets or sets a security action.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
Unrestricted	Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared.

Methods

CreatePermission()	When overridden in a derived class, creates a permission object that can then be serialized into binary form and persistently stored along with the SecurityAction in an assembly's metadata.
Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
